Applicatiouled April 17, 1915. Serial No. 22,125.

vented a new and useful Sharpening-Machine, of which the following is a specification. This invention relates to sharpening machines especially designed for usefin sharpening the-blades of. clippers such as used by barbers.

One of the objects of the invention is'to provide a `machine of this character which is simplepdurable and compact, will not readily get out of order, and which has, novel means for` holding the blade in position upon the' hone during the operation of the machine. V-

' With the foregoing and other objects in view which will appear as the Idescription proceeds, the invention resides in the c0mbination and arrangement of parts. ndin'the details of construction hereinafter c escribed and claimed, it being understood Q that changes inthekpipcise embodiment of the invention herein dislffd, can be made-within the scope of what-is claimed, without departing from the spirit of the invention;

In the accompanying drawings the preferred form ,of the invention has been shown. Y In said drawings :-Figure 1 is a. plan view of themachine, the coverbeing showh open and broken away. Fig. 2 is a section on line A-B Fig. 1, the cover being shown in closed. pos2it-ion. Fig. 3 is Referring to the gures by characters of reference 1 designates a box-like housing which may be provided with any suitable upon a table or other supporting structure,

each of these tongues having an eye 3 for the reception of a fastening screw. Arranged longitudinally within the upper portion of the housing l are parallel rods' 4 forming a track which is slidably engaged by ears 5 extending laterally from the end portions of a holder 6 in which is mounted a-/hone 7. An extension Si is formed'upon the bottom of the holder` and a spring 9 is secured at one end to'this extension and at its other end to one end of `the housing 1', this spring serving to maintain the holder normally adjacent one end of the housing.

a section on line` *cat-ing the holder, a. backing plate,

A hanger 10 extends downwardly from the extension and 1s connected by a pitman 11 to."

a crank l2 provided adjacentthe 'center of a` transverse shaft 13. Tlis shaft -is journaled within the sides of the housing 1 and has any suitable means,

it can be rotated readily. Bearing downwardly on the hone 7 is a backlng. plate 15 provided, at each corner, with av hook 16. Extending from each hook is a coiled spring 17, these springs being secured to the housing 1 close to each corner thereof. In other words, the springs extend along dive-rging lines and'itwill' be noted, furthermore, by referring to Figs. 2 .and 3, that these springs are inclined downwardly away from the backing plate l'so'that they not only serve to hold said plate constantly centered upon the hone 7, but also pull it downwardly onto the hone. The backing plate 15 can be removed readily whenever desired by unhooking the springs 17 from the hooks 16. Openings 18 are formed in ceive plugs 19.

such as a crank arm In usingthe machine herein described, 'j

two ofthe springs 17 are disconnected from theplate 15 and said plate lifted off ofthe placed on the hone and the plugs 19 are inserted into the openings 18 and into the corresponding holes in the bladeV to be sharpened after which the springs 17 are again placed in position and all of the springs will coperate to hold the blade pressed vieldingly'onto the hone. By rotating shaft 13,

The blade to be sharpened is thenthe hone will\be reciprocated under the yieldingly held blade and this reciprocation can be continued as long as desired. A

When the-machine is not in use the cover 20 can be closed, as shown in Figs. 2 and"3. What is claimed is A Y 1. The combination with parallel rods, of a holder mounted forrepiprocation thereon, a hone carried thereby, means for reciprocating 'the holder, springs diverging outwardly and downwai'dly froln the backing plate 4for holding the plate yieldingly pressed upon the hone and for holding it yieldingly against movement with the hone.

2. The combination with parallel rods, of a holder mounted for reciprocation thereon, aliene carried thereby, means for recipro- 'springs los diverging outwardly and downwardly from the backing plate for holding the plate yieldingly pressed upon the hone and for holding it yieldingly against movement with. the hone, and means det-,reliably connected to the backing plate for holding a blade between the plate and the hone.

3. The combination with a housing and guide rods therein, of a holder mounted to' reciprocate upon the rods, .:aerank. shaft, means for transmitting motion!" from "the crank shaft to the holder to reciprocate the holder, a hone upon the holder, yielding means connecting the holder to one end of the housing, a backing plate, downwardly and outwardly diverging springs connect- 'ing said backing plate to the housing and.

constituting means for holding the plate pressed yieldingly against the hone and to hold the plate yieldingly against movement with the h9ne,and means carried by the backing plate for engaging a blade to hold it between` the plate and hone.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature inthe presence of two Witnesses.
